DETACHABLY-COVERED BOOK.

SPECIFICATION forming part of Letters Patent No. 243,863, dated July 5, 1881.

Application filed March 31, 1881.

To all whom it may concern Be it known that I, WILLIAM L. DEMING, of Salem, in the county of Golumbiana and State of Ohio, have invented certain new and useful Improvements in Detachably-Govered Books; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to that class of blankbooks which have detachable covers; and it consists of the parts and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of my book-cover with the leaves removed, and showing the lip or flange attached thereto. Fig. 2 represents the body of the book or the leaves detached from the cover and provided with the receptacle or retainer for uniting it with the metal retaining lip or flange attached to the cover. Fig. 3 represents a detached view of the metal plate that is permanently attached to the back of the cover and carrying the flange or portion of the looking device.

The covers AAare composed of heavy bands of cloth or paper, as may be desired, and their back A of cloth or leather. Within the back A is incased the angle-plate O. This plate is shown detached in Fig. 3. As will be observed, the portion of the angle-plate permanently attached to and covered by the back will make a firm foundation for the flange or locking device C.

The body of the book B, as shown in Fig. 2, is formed by uniting at one end a series of half-sheets of paper of the desired size, by pasting across the end thereof, or by any other suitable means, only provided that each sheet may be readily detached without disturbing any other sheet and without mutilating the sheet det'ached. To the back of this series of leaves thus prepared is attached a back, D, provided with the flange D. This back D,

with its flange D, may be made of metal, wood,

(Model) card-board, or other material. I have found, however, a good quality of binders board to be preferable to any other on account of its cheapness, it answering every purpose as far as durability is concerned.

The cover A and leaves B being prepared as described and shown, the leaves are held firmly in one hand and the cover in the other, when the flange D on the leaves is made to slip into the flange C of the angle-plate attached to the cover. Theleaves being in place, each separate leaf may be used and detached without disturbing any other. When the last is used the head-piece D can be readily removed, and the covers are ready for the reception of another series of leaves B.

What I claim isv1. The combination, with a pair of bookcovers having their back provided with a plate, 0, formed in two longitudinal angular portions, thefree side ofone ofsaid portionsbeingformed with a flange, O, bent over on itself, of a series of leaves provided with a rigid back, D D, formed likewise in two longitudinal angular portions, one of which is secured to said series of leaves,and the other fits against the side of the series of leaves, and is adapted to interlock with flange G, substantially as set forth.

2. The combination, with a pair of bookcovers having their back provided with a plate, G,formed in two longitudinal angular portions, thefree side ofone ofsaid portions beingformed with aflange, U, projecting from its central body and bent over on itself, of a series of leaves provided with a rigid back, D D, formed likewisein two longitudinal angular portions, the free portion, which fits against the side of the series of leaves, being formed with beveled ends, and adapted to interlock with flange G,

substantially as set forth.

In testimony whereof I have signed my name to this specification in t-he'presence of two subscribing witnesses.

WILLIAM L. DEMIN G.
